Application filed April 9, 1909. Serial No. 488,868.

To all whom it may concern:

Be it known that I, Damen D. MURRAY, a citizen of the United States,residing at Duluth, in the county of St. Louis and State ofh/Iinnesota,l have invented new land 'useful Improvements inTire-Protectors, of which the following is a specification.

This invention relates to tire protectors, the object of the inventionbeing to provide a simple and effective protector shield for preventinganti-skidding chainsfroni injuring rubber tires, the protector or shieldbcing adapted to be readily applied to the ordinary anti-skidding chainwithout the use of screws, bolts or other analogous fas tening devices.

lVit-h the above general objectin view the invention consists in thenovel construction, combination and arrangement of parts herein fullydescribed, illustrated and claimed.'

In the accompanying drawings Figure l is a side elevation of a portionof a Wheel, showing a tire chain applied to the tire thereof, andseveral of the protectors or shields connected with portions of thechain.

F ig. 2 is a plan view on an enlarged scale of one of the protectors. ofthe same.

Referring to the drawing l designates a wheel, 2.a rubber tire, 3 one ofthe circular sections-of an anti-skidding chain and 4 the transversesections or portions of the chain,

Fig. is an edge view -which portions embrace the outer or tread portionof the tire as shown in Fig. l.

In connection with eachtransverse section 4 of the chain, I employ ashield orfprotector shown in detail in Figs. 2 and 3, the samecomprising a concave-convex or arched body 5 formed preferably of sheetmetal of the proper gage, the oppositeV end portions of the body beingoffset as shownl atand then extended about tangentially to the arch ofthe body to form'ianges 7 About centrally of the length of the offsetportion 6 at each side of the shield or protector, a chain slot oraperture 8 is formed and the flange 7 is centrally divided as shown at9, forming oppositely arranged slotvclosing lips or lugs 10 betweenwhich the -transverse por.- tions 4 of the chain vare adapted to beinserted in the slots or apertures 8, after which they are retained inplace' by bending the lugs or `lipslO back into the same common planewith the flanges 7. Thishas the effect of closing the entrance to theslots 8 and prevents disconnection between the protector and the chain.

In the preferred embodiment of the invention, a plurality of ribs l-lare providedon the outer surface of the protector as best indicated "inFig. 2, said ribsextending in substantially parallel planes and trans--versely of the tire and serving to obtain a grip on the surface overwhich the wheel is being propelled. The inner ribs ll are preferablyarranged at a suitable distance apart to allow the section l of thechain to lie between them, thus removing a good portion of strain fromthe retainer lips or lugs 10. The shield or protector herein abovedescribed is interposed between the chain and Vthe tire and formsan.e"ective protector for the tire by preventing .the chain fromscraping and cutting into the tread portion of the tire. After theprotectors are connected to the chain inx the manner shown anddescribed, they remain fastened to the chain in readiness for use at anytime.

I- claim:

l. rfhe combination with a tire chain embodying cireumferentialsidemembers and transverse sections connecting the side mem.- bers, of atireprotector consisting of an arched metallic body adapted to Abeinterposed between a transverse section of the chain and the tire, andmeans on said protector for attaching the same to said transversesection only of the chain.

2. A tire protector for preventing antiskidding chains from injuringrubber tires,

consist-ing of an arched metal body adapted to be inter osed between atransverse section ofthe chain and the tire, means for securing'k theprotector to such portion of the chain, and chain-retaining ribsprojecting from the outer face of said protector and extendingtransversely of the tire. l
